To all whom 'it may concern Be itknown that I, lVALLAon B. \VoLrr, a citizen of the United States, residiii at Chicago, in the county of Cook and btate of Illinois, have invented a certain new and useful Improvement in Slicing-Machines, of which the following is a specification. f My invention relates to improvements in feed devices for slicing machines, and has for one object to provide a feed device which will feed meat or other substances to be sliced toward the cutting knife. Another object is to advance the meat in response to the reciprocation of the meat carriage. Another object is to provide a device which will adjustably give any desired amount of feedfor each rcciprocation of the carriage. Another object is to provide a device whiclican be easily adjusted to vary and control the nicat carrying member. Uther objects of my invention will appear from time to time in the course of the specification.

My invention is illustrated more or less diagrammatcally in the following drawings wherein Figure 1 is a plan view of the slicing machine embodying my invention;

F ig. 2 is a side elevation in part section of in v device the line of sight being along the line of the arrow 2 of Fig. l;

Fig. 3 is a vertical section along the line :li-:fifi Fig. e;

1 Fig. 4 is a vertical sectionalong the line l-l of Fig. 2;

Fig. 5 is a detail of the adjustment indicating device illustrated in Fig. 1;

Fig. 6 is a vertical section on the line (3 6 of Fig. 5;

Fig. 7 is a vertical section of a part of the feed screw shaft mounting.

Fig. 8- is a vertical section on lines 8-8 of Fig. 7.

Like parts are indicated by like characters throughout the several drawings. A isa slicing frame. The carriage A1 is adapted to reciprocate along the tracks A2, A3 being driven by any suitable means in response to the rotation of the drive wheel A4. A is the cutting knife rotated by any suitable l driving means not shown in response to the rotation of the drive wheel At.

B is a meat plate adapted to slide along the carriage A1 toward the knife. It car-` ries a piece of meat B1 held by the clamp B1. B3 is a nut mounted on the lever B1 l* to the downward projection controlled by the thumb piece B5 so thatit may be thrust into or outl of engagement with the feed screw B which screw is mounted `for rotation on the carriage A1.

C is a cylindrical housing for the feed screw B0 open as at C1 to permit movement of the nut B8 along the screw and still afford substantial protection for the screw.

-D is a one way clutch drum or ratchet controlling the screw B6 having within it any suitable means for rotating clutch )arts not shown and, the screw B controlled tliereby, in response to rotation of the drum in one direction; but freely permitting rotation of the drum without rotating the screwv in the opposite direction. D1 is a. chain, one end anchored at D2 in the channel Da of the drum the other end secured as at D4 to a spring 5 which lies wit-hin a housing DG secured on the end of the carriage A1, and has the depending part D7 which overhangs the side-of the frame. A. which presents an open end in the diiection of the drum. The sprino D is secured by any suitable means at ls to the opposite closed end D of said housing. D1 is a hand crank keyed to the clutch D. E is a second chain secured as at E1 to the periphery of the drum, within its channel, its opposite end secured as at E2 to .a segment E1 )ivoted at 7 of the carriage A1. Une 'arm lt" of the segment lcarries adjacent the point of securing of the chain a roller F whose purpose will later appear. adapted to contact the cam shaped stop E7 which is adjustab mounted on part D1. The stops E and 1 coperate to limit the rotation of the segment.

G is an adjustment screw mounted for rotation in any suitable manner adapted to be operated by a hand crank G1 connected to E6 is a stop on the segment E3.

it by a. shaft G2. rlhe free end of the screw ('lr rotatably meshes with and penetrates a depending stop or cam H slidably supported by any suitab e means on an angle iron H1 secured to the framework A of the slicing machine.

In my preferred form I illustrate the cam as slidably secured to the lower side of said angle iron H1 by means of a plurality of screws or stops 2 which penetrate a slot H3 inthe. horizontal surface of said angle iron. Between the enlarged heads H4 ofthe screws and a plate which rides on the top of the angle iron, are the compression springs. H whlch serve to hold the dependin camin close but slidable engagement wit Vthe lower surface of the angle member. Secured tothe an le iron H1 are the adjustable stops H8, H9 Wiese purpose will later appear.

' .The forward face of the cam H opposite its engagement by the screw G, is shaped to form an arcuate, concave runway H" lying 10 in the same vertical plane and adapted tol l I of said housing is a pinion I5 in mesh with said worm and secured in place by a ,pivot 'screw I". Keyed'to the pinion and rotating about said screw is a' plate I7, its f center sunk to receive the enlarged head 1a of the screwI". Secured to the topof said lling a circular opening *K1 in the plate K which forms the top of said housing. Although I have illustrated in my drawings an operative device, it may be obvious that 'many changes both in form, size and 'arrangement of parts may be made without departin from the spirit of my invention, and I wish therefore that my drawings be taken as in a sense diagrammatic.

Where in the specifications and claims I i have used the vexpression meat plate, I mean of course`that the material that is eing cut, and I of course do not limit myself to a plate which 40 will carry.meat,'a's. my machine may be used equally well in slicing a large variety of materials. f y The means for reciprocating the meat plate comprise a crank, a connecting rod anda train of gears and is driven by a vpower wheel A4. Thisarrangement is not shown as it is notl part of the present invention which is directed primarily toward a mechanism which may be applied to any j reciprocating. plate slicing machine irrespective of the manner or c means of producing` such reciprocation. A igs. 7' and 8 illustrate in detail the structure of the clutch drum or ratchet D.

I The-member D' contains the bearing L for the shaft B7 which' carries the feed screw. This-sleeve is held in position by the set screw L1. L? is an extension projecting ,from the end of the feed screw, supporting the shaft on which is mounted a sleeve L3 carrying at one end the handle L1, and at the other end a clutchplate Lf. The clutch plate Lts has fingers Le L6 interposed between cam surfaces L7' L1, balls L? LB- adapt- 05 ed to rollalong these cam surfaces being late is the indicating dial I9 completelyl plate which supportsof the crank G1 and the screw The use and operation of my invention are as follows: l

`The meat plate is placed on the meat carriage so that it may slide therealong. The

nut by manipulation of the leveris thrown 1n engagement with the feed screw. The meat 1s then placed on the meat plate and locked in position by the clamp. The operator then rotates the drive wheel causing a reciprocation of the meat carria e back and forth toward and from the knife. Meanwhile the knife is rotated so that as the meat is fed toward it, a' slice may be cut olf. It is lnecessary of course that upon Aeach reciprocation of the meat plate, the meat be fed forward a certain distance equal to the thickness of the slices. This feed is caused by a progressive rotation of the ,feed screw B1.

By referring to Fig. 2, it will become evident that as the carriage is moved to the left, after the meat cutting`excursion, the roller on the segment will engage lthe concave face of the cam H. As the meat plate continues its excursion, the roller will ride down the cam, and the segment will be rotated to the position' shown in the dotted J `other substance to be cut will be advanced by the feed screw and the nut .controlled thereby, toward the knife, in preparation for the next cutting excursion. B rotation the cam can be withdrawn toward the left, thus shortening the are through which the segment rotates, and the amount of rotation of lthe screw. The thickness of the slice cut, is thus positively controlled by the operator, and is indicated on the dial face con-l trolled by the rotation of the screw G.

When a new cutting excursion is begun and the carriage plate returns to the rightof the machine, the roller rides up the cam, the segment returns to upright position, and the chain vE is wound back on the drum D by the action of the Spring on the chain D1.

This rotationA of the drum has no'eifect on the adjusting screw, since the clutch D is a one way clutch, and does not control the feed screw during this return rotation.

lOl

`The excursion'of the cam is limited by .the stops H8, H which may be slightly adjusted, if necessary.

The feed screw is further manually controlled by the hand crank D10 by which the meat can be advanced toward the knife, regardless of the automatic feed.
